Director Brad Bird looks pretty cheerful in this featurette, considering he’s in charge of keeping one of the world’s biggest stars alive while he leaps, climbs, and dangles off the tallest building in the world. For the fourth installment of Mission: Impossible (no one has yet properly explained to me just what a “ghost protocol” is but I don’t care, I’m in), Tom Cruise apparently must find his inner Spidey and scale the Burj Khalifa in Dubai, which stands at 2723 feet (gulp). This stunt really does look death-defyingly cool — lots of tourists caught the action themselves and it even made the local news.

As for Cruise, he looks pretty relaxed in those wires. The film (you can check out the trailer here) also stars Jeremy Renner, Simon Pegg, and Paula Patton, and will be in IMAX theaters Dec. 16 and everywhere on Dec. 21.
